Not a match-goer... on the basis of a few thousand miles... so I might be talking a bit out of turn here.
But I fear that not booing the sly bastard would be as dangerous as booing him.
The media will write/say/turn this into anything they want... no matter what the truth is, and no matter what evidence might be there in plain view. We've already seen that.
It probably wouldn't even help if he was clapped, cheered or totally ignored... they'll just turn it into whatever fits. Even should every single Manc out there get the same treatment, some would probably say it's just to mask the supporters true intentions.
The reason I see not booing as dangerous, is that, in my mind, it would mean they've achieved what they wanted. They would basicly have dictated how the crowd should act on a matchday such as this, and that is giving them far too much power. They told us to sit pretty. Can't really think of a better reason not to.
The way I see it, as long as it's kept within the limits of the law and somewhat in the vicinity of common decency, give the fucker hell. We only answer to the King, our fellow supporters, and our conscience.
Fuck the rest of them. Bargepole style.
Yes, I'm still bloody livid about what they did to Luis. And it all started with this little prick.
